Top explanations for Spatial Summation
Synaptic & Junctional Transmission — Ganong's Review of Medical Physiology▶ 25:26And build towards thresholdAnd spatial summationSpatial summation is about adding up inputs from different places at the same timePhysiological Development and Phenotypic Plasticity — Animal Physiology: From Genes to Organisms▶ 19:57ExactlySpatial summation is when multiple different presynaptic neurons fire at roughly the same timeTheir individual EPSPs and IPSPs arrive at different spots on the postsynaptic neuron, but converge at the axon hillock and add together…Neurons: Cellular and Network Properties — Human Physiology: An Integrated Approach▶ 36:12And this integration happens in two waysSpatial summation occurs when multiple graded potentials from different locations, different spaces on the neuron, arrive at the trigger zone at nearly…So if two separate EPSPs arrive simultaneously, their amplitudes add together
